Use a neutral tone (not overly formal or informal).

Use correct Russian grammar — appropriate cases, suffixes, and endings depending on context.

For the following technical terms, use these specific translations to ensure consistency and clarity across the documentation:

* production (meaning production software or environment): продакшн (do not change the ending, for example, translate `in production` as `в продакшн` (not `в продакшене`))

        assertEquals(start1, start2, "Start time should remain constant");
        assertNotNull(start1, "Start time should not be null");
    }

### Feature

**Purpose**: Test the base AbstractExtractor functionality.

**Key Test Areas**:
- `validateInputStream()` method behavior
- Exception types and messages
- Stream consumption (should not consume)
- Consistency across multiple calls

**Test Count**: 11 tests

**Key Scenarios**:
- ✅ Validates non-null streams
- ✅ Throws CrawlerSystemException for null
- ✅ Called during getText execution

            md5.digest(null);
        });
    }

    @Test
    @DisplayName("Should produce consistent hash results")
    void testHashConsistency() {
        // Given
        String input = "Test consistency";
        byte[] data = input.getBytes();

        // When
        MessageDigest md5_1 = Crypto.getMD5();
        MessageDigest md5_2 = Crypto.getMD5();
        byte[] hash1 = md5_1.digest(data);
